SIMATIC Memory Card required for operation of the CPU

The CPU 1511-1 PN is the cost-effective entry-level CPU for standard and fail-safe applications with medium requirements for processing speed and speed of response in discrete production technology. With its work memory size, this CPU is also suitable for medium-sized applications. It can be used as a PROFINET IO controller or as distributed intelligence (PROFINET I-Device). The integrated PROFINET IO IRT interface is designed as a 2-port switch, enabling a linear topology to be set up in the system. In addition, the CPU offers comprehensive control functionalities via easy-to-configure blocks as well as the ability to connect drives via standardized PLCopen blocks.

The CPU 1511F-1 PN has:

A powerful processor:
The CPU achieves a command execution time as low as 60 ns per binary command.

Extensive work memory:
230 KB for program, 1 MB for data

SIMATIC Memory Cards as load memory;
permit additional functions such as datalog and archives

Flexible expansion options: single-tier configuration with max. 32 modules (CPU + 31 modules)

Display with functions for

Display of overview information such as station name, higher level designation, location designation, etc.

Showing display settings

Setting IP addresses

Setting date and time

Switching the operating mode

Resetting the CPU to factory settings

Disabling/enabling the display

Enabling of protection levels

Display of safety mode, overall signature and date of the last download with signature change

PROFINET IO IRT interface for connecting distributed I/O via PROFINET

Supports PROFIsafe in centralized and distributed configuration

Performance

Faster command processing, depending on the CPU type, language extensions and new data types

Even shorter response times of the CPUs due to considerably faster backplane bus

Powerful network connection:
Each CPU is equipped with PROFINET IO IRT (2-port switch) as standard interface.

Integrated technology

Connection of analog and PROFIdrive-capable drives via standardized blocks (PLCopen)

Support of speed-controlled and positioning axes as well as external encoders

Trace functions for all CPU tags, both for diagnostics in real time and for sporadic error detection

Comprehensive control functionalities, e.g. easily configurable blocks for automatic optimization of the control parameters for optimum control quality

Security Integrated

Password-based know-how protection against unauthorized read-out and modification of program blocks

Copy protection for tying individual blocks to the serial number of the SIMATIC Memory Card: The block can only run if the configured memory card is inserted in the CPU.

4-level authorization concept:
Communication to operator panels can also be restricted.

Manipulation protection:
The controller recognizes changed or unauthorized transmissions of the engineering data.

Design and handling

Display of overview information:
E.g. Station name, plant designation, location identifier, etc., diagnostic information, module information, display settings.

Possible operations on the display:
Set addresses, set date and time, select operating mode of CPU, reset CPU to factory settings, disable/enable display, activate protection levels.

Integrated system diagnostics

System diagnostics information is displayed consistently and in plain text in the display, TIA Portal, operator panels and web server, even for messages from the drives, and updated even if the CPU is in S** mode.

Integrated in the firmware of the CPU, no special configuration is required

SIMATIC Memory Card (required for operation of the CPU)

Used as plug-in load memory or for updating the firmware.

Also for storing additional documents or csv files (for recipes and archives)

Creation of data blocks for storage/reading of data via SFCs of the user program

Datalog (archives) and recipes

Storage of csv files for recipes and archives on the SIMATIC Memory Card;
easy access to plant-relevant operating data using Office tools and via web server

Easy access to configuration data of the machine by means of a web browser or SD card reader (two-way data exchange from and to the PLC)

Programming of the standard program section
